Free OCPP 1.6J server for the ABB Terra AC Wallbox charger

Point your ABB Terra AC Wallbox (7.4 / 11 / 22 kW) to our OCPP 1.6J server to control who charges, measure kWh per session, and start or stop charging from your phone. Free with EzGYM.

The ABB Terra AC Wallbox (7.4 / 11 / 22 kW) includes network connectivity with the standard OCPP 1.6J protocol (JSON over WebSockets). Using OCPP, the charger talks to a central server to validate RFID cards, report live kW power and log the kWh of every session. EzGYM is that central server, for free.

If you run a gym, sports club or customer parking lot, you can require RFID authorization so the ABB Terra AC Wallbox stays locked to strangers: when a member taps their card, EzGYM checks if their membership is up to date and starts charging while they work out.

If you operate a distribution company or delivery fleet with electric vans, you can link the ABB Terra AC Wallbox to your vehicles to track exactly how many kWh each driver charged at the depot and the cost of every session.

From the web dashboard or your phone you can also trigger RemoteStart / RemoteStop and unlock the connector with a single tap, without paying monthly per-plug fees.

How to set it up

  1. 1 Create your free EzGYM account and go to EV Chargers.
  2. 2 Add your ABB Terra AC Wallbox with its rated power (7.4 / 11 / 22 kW) and choose whether to require RFID or set a kWh tariff.
  3. 3 Copy the unique OCPP URL given by the app (wss://ocpp.ezgym.net/ev…).
  4. 4 If the charger asks separately for the “Charge Point Identity”, “ChargeBox ID” or “Identity”, enter the ev… identifier there (the end of the URL) and leave just wss://ocpp.ezgym.net/ in the URL.
  5. 5 Open TerraConfig (Bluetooth) › OCPP Server › External Server › Custom Server on the ABB Terra AC Wallbox, paste the OCPP URL and reboot the charger: within seconds it shows Available in EzGYM.

Before you start: on ABB Terra AC chargers the custom server option (“Custom Server”) only shows up in TerraConfig once ABB enables it. Ask your ABB representative or installer, and once enabled enter the wss://ocpp.ezgym.net/ev… URL EzGYM gives you. Registration can take up to 10 minutes.

Frequently asked questions

How do I connect the ABB Terra AC Wallbox to EzGYM?

Add the charger under EV Chargers in EzGYM and copy the unique OCPP URL shown in the app (wss://ocpp.ezgym.net/ev…). Then paste it into TerraConfig (Bluetooth) › OCPP Server › External Server › Custom Server on the charger.

Does the ABB Terra AC Wallbox use wss:// or ws://?

Use the URL that starts with wss:// (port 443, encrypted): it is the one the app gives you. If your ABB Terra AC Wallbox firmware only accepts plain ws://, write to us with the brand and model.

Can I lock the ABB Terra AC Wallbox so only authorized members or drivers can charge?

Yes. Enable “Require RFID card” on the charger settings in EzGYM and the ABB Terra AC Wallbox will verify every card in real time before delivering power.

How much does the OCPP server cost in EzGYM?

Nothing. The OCPP 1.6J server, RFID card validation, remote commands and kWh session history are free in EzGYM (up to 20 chargers per account).
